New Family of Exotic $\Theta$-Baryons

Abstract

From the interpretation of the $\Theta^+$ baryon resonance as an excitation of the ``skyrmion liquid'' with SU(3) flavor symmetry $\bar{10}$ we deduce a new series of baryons, $\Theta_1^{++}$, $\Theta_1^{+}$ and $\Theta_1^0$, situated at the top of the 27-plet of SU(3) flavor, with hypercharge Y=2, isospin T=1 and spin $J=\frac32$. The mass of $\Theta_1$ is estimated 55 MeV/c^2 higher then the mass of $\Theta^+$ and its width at 80 MeV. We also discuss the other baryons from the 27-plet.
